Benefits of technology
This approach ensures rapid, high-quality part formation with refined grains, reduced thermal and residual stress, and enhanced mechanical properties, improving manufacturing efficiency and stability while preventing material flow and collapse issues.
Problems solved by technology
In order to solve the problem that the internal defects generated during the forming process of the parts in the existing rapid manufacturing such as pores, incomplete fusion, cracks and shrinkage porosity result obvious additive effect of the residual stress inside the parts in the melting deposition forming with the increasing number of scanning layers, which cause the parts to crack and deform easily.

embodiments
[0028]According to FIGS. 1 and 2, the embodiment relates to a method for rapidly forming a part using combination of arc deposition and laser shock forging, including the following steps.
[0029]1) A 3D model of the part is drawn and imported into a simulation system of a computer 1. A preforming part model is divided into one or more simple forming units by the simulation system. A forming order of the forming units is determined. The forming units are laminated and sliced in a stack direction. The data is processed according to the laminated slices to generate a numerical control code for processing slices respectively. As shown in FIG. 1, the 3D model of the part is drawn by using the simulation software in the computer 1, or using other 3D drawing software (such as SolidWorks, UG, etc.) to draw the 3D model and imported into the simulation software. The preforming part model is divided into one or more simple forming units. The forming order of the forming units is determined. The...
